Use of solar energy
Have you ever fried an egg on your roof? No one has ever fried it but it can be fried if you want. You can also try once if you want. In low humidity the day must be very hot and the sun will hit the roof for several hours. You can also try this egg frying test in another way. Place a flat aluminum pan in the sun. When the pan feels hot to the touch, drop a piece of butter into it. Break the egg very carefully and drop it on the melted butter. See how quickly the egg is fried.

The energy of the sun's rays, the heat generated after falling on the above place or on the metal vessel, made it possible to fry eggs in this novel way. In this experiment you can imagine what awesome power is hidden in the sun. In fact, it is with this energy of the sun that life on earth has originated. We would not be able to survive if it were not for the sunlight that reaches us from a distance of 930 million miles at a speed of 1,86,000 miles per second in a total of eight minutes. Plants grow by collecting energy from sunlight and we live by eating the seeds, stems, roots, leaves etc. of these plants.
Water absorbed by the sun at a temperature of 100 degrees Celsius dries up and takes the form of flammable vapor. And these fiery vapors return to us as rain, fog, snow and sleet. This water is essential for growing crops on land. Furthermore, crop plants require sunlight to survive, grow and produce their carbohydrate food. We also live by eating these carbohydrates made by plants. Billions of years ago, forests or marine life, which later disappeared into the Earth's interior, were created in the presence of the sun. The coal, natural gas, or mineral oil that we extract from the ground are naturally derived from decaying plants or marine life. These elements of natural energy are gradually depleting. Mineral energy sources are gradually running out. Scientists have already discovered nuclear energy. Yet more and more new energies are being explored. Especially in the most remote places of the world, scientists are searching for what energy can be gifted for human work. Due to the discovery of molecular energy, we have forgotten that the main source of our energy is the sun. And from this sun we get a huge amount of energy.
99% of the sun's energy is wasted after reaching the earth. In arid countries where no vegetation grows, in the remotest underdeveloped countries, where the sun shines almost every day, there is a greater waste of solar energy. Scientists can convert solar energy into operational energy and store this energy for future use. But they are unable to replace them due to lack of necessary initiatives. We still cannot think of all the countries of the world as a global village. We are destroying ourselves in the name of sovereignty. We are making weapons of mass destruction. I can't or don't want to distribute the economy of all the countries of the world fairly. We have one country building robots for war and the other using electromagnetic technology to stabilize and destroy Robert's functionality. Entry tank opposite the tank. Hyper sonic missile with entry laser fiber as opposed to laser beam which is never detected by radar. Instead of gunpowder, we are using photon particles that can eject electrons from metal and that particle or wave can penetrate any wall. Unlike a fighter jet, a network jammer is a fighter whose waves can block the network and the fighter pilots can no longer operate the fighter. Everything is set up to destroy ourselves. We continue to politicize and fight religion even in today's age of modern technology. This is just a story of misuse of physics. As a result of the misuse, we are wasting the energy stored in our earth day by day. But what will we do when we run out of all these natural resources found in our nature?
How were the Roman fleets burned with the help of solar energy?
Around 214 BC, when Archimedes discovered the great power of the sun's rays, the Greek mathematician lived in the city of Syracuse when he revolted against the Romans. When the Roman fleets anchored just off the coast, they came within reach of Archimedes' invention of the solar system. He made a mirror composed of many sheets of very smooth brass and glass thick enough to be placed so that the mirror could collect the sun's rays and turn them into concentrated energy, and by reflecting them on the wooden fleet, he set fire to it. It was in this manner that the fleet was burned and the city of Syracuse was saved. However, experts differ on this matter as it has not been proven with current technology. As for what kind of technology he used is lost to time. But there is no doubt that he used the rays of the sun.
In today's civilization we want to harness the rays of the sun for the benefit of mankind. All the scientists of the world are conducting research in an attempt to use the energy of the sun for various welfare of the people. One attempt to harness solar energy is the use of solar reactors. Dr. Felix Tremby of Saint Louis, France built the world's largest solar reactor. A large flat mirror, placed at an angle where the sun's rays are reflected to the mirror. The energy from that drop falls to another opposite location and the heat energy is utilized from this location. Where 5000 degree Fahrenheit heat is generated, such heat can melt any metal, burn any wood, burn any living thing to ashes.
Now imagine that if such heat can be concentrated on a quaternary water, what form will be created? The water will bubble and boil. Very quickly that water will turn into steam, this steam can be properly operated to run a steam engine and with that steam engine electricity can be generated and that is at a very low cost. Our natural resources will save fuel, nuclear waste from nuclear reactors will be emitted less, less radiation will be spread in river water, our forests will be protected and animals will be protected. As far back as 1901, when such a solar-powered steam-powered broiler was tested for pumping sun-scorched soil for agricultural purposes in Arizona, USA. The sun's rays falling on one acre of land in the desert at noon is equal to 4000 horse-power and this power can easily drive a large car.
Factory plants can also be run with solar energy. There is no work where we can do that by harnessing solar energy through nanotechnology. Maybe we will understand when our natural environment is almost destroyed when the ice of the Antarctic continent melts and the lowland countries are submerged in water. The plants that exist in our nature, factories of oxygen for our survival, will be destroyed. Due to the increase in temperature in nature, the trees will no longer grow normally, the ultra violet rays of the sun will not be directly reflected on our weight level and will penetrate it and fall to the ground, the seeds will dry without sprouting. That's when we will understand the value of solar energy.

Solar powered batteries
Scientists at Bell Telephone Chemistry built the tiny solar-powered battery in a metal box filled with a very thin layer of crude silicon. When a 1/10,000 inch layer of silicon thin film is penetrated by the needle beam, impurities are removed from that layer. And positive and negative levels are created, thus converting solar energy directly into electrical energy. But its usage is only 2.75 percent. Zero share in some countries. This battery is safer and more efficient than the gas engine or motor vehicle engine.
The telephone company used solar-powered batteries for 8 rural telephone lines in American and Georgia states.One square yard of thin silicon sheet produces 50 watts of electricity. Scientists are striving to generate more electricity from the sun, which sends 1,000 trillion kilowatts of energy to Earth a day. Scientists are using silicon batteries powered by light to invent wireless devices to maintain permanent electrical connections, unmanned river cleaning lances, mobile phones, calculators, home electricity, etc. Electronic devices are powered by direct conversion of sunlight into electricity and can be stored like conventional batteries. To charge the battery, the silicon sheet has to be left in front of the sun for an hour and the electricity that will be accumulated in this work can keep the electronic equipment up to 50 hours automatically. Sun rays fall directly on 70 thin layers of silicon for 24/7 power connection at home or office. These thin sheets convert sunlight directly into electricity and additional batteries are arranged in trays to store the electricity so that they are fully charged even when the sun is not shining.
A similar solar battery is attached to Earth's artificial satellites. As the metal sphere orbits the Earth, the battery harvests energy from the sun's rays to generate electricity to power the plants inside. Concentrated heat from solar energy is collected to investigate the reaction of heat generated on metals. Washington D.C. The National Bureau of Standards and Applied Solar Energy's Arizona chemistry lab generates heat of 6300 degrees Fahrenheit. Such heat melts the metal into its pure form and burns away any impurities. In this, scientists can gain various knowledge about pure metals.
Such knowledge is extremely useful for future projectiles for future space travel. 6,300 degrees F of heat will melt the entire shell of any moving rocket. Various metals have been tested in such solar furnaces but none of the metals or alloys can survive temperatures of 6,300°F. Scientists are experimenting with their own metal. In order to develop such heat resistant alloys. With which you can build rockets for space observation that can survive high temperatures. The ideal arrangement for conducting such research is solar reactors, which can easily generate heat of 6,300 degrees Fahrenheit. To research metallurgy, to build high-speed aircraft out of very high metals, to experiment with new metals, and to imagine what kind of heat nuclear weapons would generate, great heat was needed. The American Air Force invented a solar reactor. It can generate heat up to 8,000 degrees Fahrenheit.
Heat and energy can be obtained from the sun in the uninhabited wilderness of the ice-covered North and South Poles. At present, fuel has to be transported by plane to such desolate ice-covered countries. Dr. R. W., who researches the feasibility of using solar energy in the North Pole. According to Gardel, it costs $5,000 an hour to airlift 15 drums of fuel to the North Pole at once. He and his colleagues believe that energy can be easily harvested from the sun's rays, which are available for 24 hours a day in May, June, July, and August, and for 9 hours a day in March, April, September, and October. Sunlight can be harvested during the hotter months and stored for the dark months of November, December, January and February.
Dr. Maria Tex was one of the scientists who pioneered the modern solar reactor. The furnaces are covered with asbestos and are heated by a sheet of metal that generally reflects light. Delicious biscuits, puffed bread, chicken, noodles etc. are produced in solar furnaces of such factories. Modern umbrella-shaped solar cookers made of aluminum with iron frames have emerged for outdoor cooking. The umbrella is opened and placed upside down. The cooking vessel is placed on the head of the umbrella butt. The sun's rays strike the inside of the umbrella and reflect back onto the container. The pot is heated from 350 degrees to 450 degrees. However, this furnace did not gain much popularity because it was annoying to bring sunlight into the house. That's why at present the thermal energy of the sun on the roof of the house is converted into electricity and that electricity is used in induction stoves.
How to keep the house warm with the help of solar energy?
Experts have actively researched how to heat a greenhouse or a glass room or office with the help of solar energy. Although we keep our homes warm in winter with room heaters. A residence in Connecticut, New Mexico, and an office in Albuquerque were among the first to install solar heating systems. An industrial plant in Tokyo, Japan gets its heat and hot water from the same source. If you've ever been cooped up in a greenhouse or a parked car on a hot summer day, you'll easily understand how the sun can keep patios warm. Proper control and distribution of heat to keep warm is a problem. Heat is collected by means of a flat sheet of water-filled tubes. The sheet is covered with thick glass to concentrate the sun's rays. The sun's rays heat the water inside the pipes and the hot water is conveyed through various pipes to the pipes inside the house and to the radiators. You may be thinking how is this possible in the absence of sunlight at night or on a cloudy day or on a cold day? Solar energy specialist engineers have solved this problem. One solution is to store hot water in an underground tank; Another is to arrange an electric generator to produce electricity with a solar engine and store that electricity in a battery. Retention of the sun's heat in chemicals and rock fragments.
Many glass manufacturers are so committed to using solar energy that they are already setting up research departments to test different types of glass to test what kind of glass will be needed to heat homes and factories with the sun's heat. Scientists hope that the sun can help increase the share of Earth's drinking supply. You may have heard that underground water levels are going down and water shortages are occurring in major cities around the world. Many of the world's deserts could be converted into much-needed agricultural land if desalination projects could be implemented in arid lands to turn saltwater into fresh water. Of course, seawater can be desalinated in a distillation process, but such an expensive distillation process would be a difficult economic challenge given the millions of gallons of water needed to operate the swach project. When people drift aimlessly in the sea of life under the pull of ghosts or in the wind, then with the help of sun rays, they quench their thirst in salt-free water by evaporating the sea water.
You can also separate pure water from salt water with sunlight if you wish. Place a large pot flat on the ground. Fill the pot with salted water and cover the large pan with a slanted glass sheet. Most of the lower part of the lid should come out from the edge of the pan. Place a container under the protruding lid to collect the desalted water. When the sun's rays fall through the glass into the large cauldron, the water will heat up and condense in the form of steam in the form of droplets on the glass lid. And it will slowly build towards the slope and the pure water will come and accumulate in the container kept there. This water is salt free and very clean. When all the water has evaporated from the pan, a layer of salt will be visible at the bottom of the pan.
Salt is still collected in this way when the water evaporates in the sun by burning the salt of the sea and the salt layer falls from there. It is possible to harvest salt and fresh water from there using sunlight technology, and we can market fresh water and salt at low cost. If solar reactors are used and desalinated sea water is used to supply cities and agriculture. That is, separating pure water and salt from sea water through solar furnace heat and pumping that pure water through solar power or solar furnace and sending it to different cities or sewage projects. There will be no need for separate electricity here. In this, we do not have to raise millions of barrels of water from the ground and do agricultural work and market. The water level under the ground can be brought back to normal, and our natural environment will be healthy. Solar scientists are exploring a low-cost way to desalinate seawater through evaporation, but until heads of state take notice, the process will remain on the web. Because of atomic energy we have forgotten that the sun is the source of all energy.
Solar and wind power to increase rain in deserts
Putting wind turbines on the edge of the Moroccan desert, large numbers of solar panels and wind turbines in the Sahara desert will have major impacts on rainfall, vegetation and temperature, researchers say. They found that wind turbines can double the amount of rainfall in the region. Scientists say the large-scale expansion of this renewable energy will transform the Sahara region itself. Scientists tried to see what would happen if this 9 million square kilometer area could be covered with solar power panels. A solar power panel has a similar effect although it will work differently. They focused on the region because the amount of solar and wind energy that can be converted into electricity from this vast sparsely populated area is close to that of the Middle East and Europe. According to the researchers, the amount of electricity that can be obtained from the large-scale installation of renewable electricity in the desert will be four times the current amount. Previous studies have shown that panels and turbines installed for wind and solar power have an effect on temperature. But this study provides further evidence that these effects also affect plants. The head of researchers at the University of Illinois on this issue. "The results we get from our model show that these solar and wind power plants in the Sahara will increase rainfall, especially in the Sahel region. The annual rainfall will increase from 20 millimeters to 500 millimeters. As a result, the vegetation production rate will increase by 20%," said Yan Li. The study found that in the Sahl, a semi-arid region south of the Sahara where the wind power plant was located, rainfall increased by 1.12 millimeters per day.
How do turbines and solar panels increase rainfall?
In wind power, the rotation of a turbine fan mixes the hot air above the atmosphere. This in turn causes evaporation, causes precipitation and helps plants grow. This increases the density of the air and causes the turbine to spin and blow the air into low pressure areas. And as a result, the air cools, humidity increases and rainfall increases, he explains. According to the research report, solar panels mainly reduce the reflection of sunlight on the earth. This is known as the albedo effect. The positive albedo effect increases rainfall by 50% and helps in vegetation growth.
How will people benefit?
Very well, say the researchers. The model suggests that increased rainfall will bring about a sustainable change in agriculture in the region. The growth of plants will meet the food shortage of livestock, increasing their numbers. Many poor people live in the desert regions of the Sahara, the Sahel or the Middle East. And there such changes will provide permanent solutions as well as electricity, food and water. The heat generated from those turbines and solar panels won't have much of an effect. The warming caused by these local wind and solar power plants is negligible compared to the increase in temperature due to greenhouse gasses.
Are these types of renewable energy plants viable on a small scale?
Scientists looked for similar effects in desert regions on the other side of the globe. They found that solar panels and wind turbines on a small scale do not have much of an impact on nature. Such activities are more effective on a larger scale. The main message of the scientists' research should reach the general public, policy makers and investors. So that solar power and wind power plants have a huge positive impact on society, environment and environment.
